Common Groundwater Contaminants Explained

Understanding what might be in the groundwater on your site is a sensible first step for any site owner, developer or manager.

Petroleum Hydrocarbons

Groundwater contamination from the use of Petroleum Hydrocarbons (PHC) such as Petrol, Diesel and Heating Oil on sites across the UK is commonplace. Typically this has originated from a leaking Underground Storage Tank (UST) at a site that was once a Petrol Station, Haulage Depot or other Industrial Yard.

Chlorinated Solvents

These contaminants are typically made up of Solvents (Chlorinated), which have been used in a variety of processes including dry-cleaning, metal degreasing and engineering-related activities. The contaminants mentioned here are dense and will sink to the bottom of the water table, making them difficult to locate and subsequently treat as part of a groundwater remediation project.

Heavy Metals

Heavy metals found on former industrial sites, tanneries, and mining spoil include lead, arsenic, and chromium. Heavy metals are adsorbed by soil particles, but can leach slowly into groundwater, posing a direct threat to Drinking Water Sources.

Nitrates

Nitrates in Groundwater, a Problem Affecting Rural Sites. The source is typically agricultural fertilisers, but can also come from inadequately designed and maintained septic tanks. Nitrates are a very soluble compound and can easily pass through soils that are sandy or made of chalk.

PFAS Forever Chemicals

PFAS Forever Chemicals – Commonly Found on Former Fire Training Areas and Other Sites. These cause significant concern due to their persistence within the environment, detection at extremely low concentrations and continued exceedance of safe concentrations for human consumption.

Phenols and Coal Tars

Phenols and Coal Tars: Former Gasworks and Industrial Sites. Phenolic compounds and coal tars, such as are found at sites of former gasworks, coke works and railway sidings are very toxic to fish and other aquatic organisms. Also, it is very toxic to humans. Often found in very dense hotspots and, therefore, require very accurate site investigation to define the contaminated groundwater ‘plume’ prior to commencement of any remediation works.

Making a few early decisions on site and then having them evolve is far easier than trying to make all of them later on.

How long does a timber frame house take to build?

The construction of a timber frame home can take anywhere between several months and several years to complete, depending on the complexity of the design, the number of professionals involved in the project, and the materials used.

The construction of a new house can be a fascinating experience for many people, especially when they are asked one of the most basic yet needed questions: how long will it take to build?

In addition to the potential for reducing the environmental impact of building a structure through the use of timber frames, the construction of such buildings can also happen at a faster rate than would be possible with other methods of building a structure.  For instance, much of the construction of the timber frame of a building is performed in an off-site location.  Therefore, the remainder of the building of the structure must take place following the installation of the timber frame.

The design and planning stage of the project typically takes several weeks or months to complete, depending upon the complexity of the house’s design and how quickly decisions are made during the design process. Following the completion of the design, manufacturing of the components of the house will begin in a controlled factory environment, while construction of the house’s foundation and other elements will happen on site. For Timber Frame House Kits, visit merlintimberframe.co.uk/timber-frame-kits/

When the frame arrives, the transformation is dramatic. The sections of the frame that may have taken weeks to construct on site can be erected in a short period of time. This allows other tradesmen who need access to the interior of the house to begin their work sooner than they would have if the frame was still being constructed on site.

In short, while timber frame may not lead to an instantaneous completion of every build project, the process of building a home with timber frames can still be streamlined for those who plan well in advance.

Brise Soleil Fixings and Support Requirements

External solar shading can pose structural demands on building facades. Importantly, fixings and support to external solar shading systems will require as much consideration as has been given to the design of the louvres.

Account for All Loads

Fixed elements, such as those of an external solar shading system, must be able to withstand two types of forces. The first of these forces is that of the dead load (the weight of the solar shading system) and the second is that of wind uplift. In many cases the force of wind uplift can be greater than that of the dead load. This must be taken into account by the designer of the fixed elements.

Choose the Right Fixing Material

Stainless steel fixings can be used on most substrates and create a neat and clean finish. Thermally broken aluminium brackets can also be used to minimise cold bridging through the facade where the Brise Soleil system passes through the insulated facade. The choice of fixings will also depend on the substrate (concrete, steel frame, masonry etc.) and so anchor types and embedment depths will need to be different for each.

Allow for Thermal Movement

Movement joints will typically be included in a fixings design for a Fin and/or Blade system as Aluminium expands and contracts due to temperature changes. If the system is to run for a number of meters, then provision will be required for expansion at regular intervals. This may be in the form of small expansion gaps in the façade and/or fixings.

Check Cantilever and Spacing Limits

The maximum cantilever for Fin and blade systems is determined by the section size. The bracket spacing also affects the deflection and load distribution of the system. Refer to the manufacturer’s load tables for the recommended bracket spacing.

Get Structural Sign-Off

As fixing designs for external solar shading form part of the overall fabric of a building structure, the necessary structural sign-off by a qualified structural engineer will be required. Solid fixings are the part of a shading scheme that nobody sees but will be safe and straight for generations to come. Guidance on what is required can be found in the structural sign-off guidance issued by the Institution of Structural Engineers. There is more on Brise Soleil at //alusystems.uk/brise-soleil-solar-shading.

The solid fixings are actually the unseen component of the exterior solar shading scheme and are, in fact, the solid component that can last for decades and remain safe and sound.

Four Sheet Metal Cutting Processes

The cutting process used in sheet metal fabrication plays an integral role in the final result. Different methods are suited to different materials, thicknesses, and applications, so choosing the most appropriate technique can improve a component’s quality and cost-effectiveness.

Here are four of the most widely used sheet metal cutting processes.

Laser Cutting

Laser cutting, like that offered by sheet metal fabricators such as dkmsheetmetal.co.uk/, uses a focused beam of light to produce highly accurate cuts with smooth edges.

It’s the ideal option for intricate designs and tight tolerances, making it a popular choice for industries that require precision-manufactured components. It’s also economical and sustainable as it minimises material waste and requires little post-processing.

Waterjet Cutting

Waterjet cutting uses a high-pressure stream of water to cut through sheet metal. Because it generates no heat, there’s no heat-affected zone, so it’s suitable for materials that could warp or lose their properties during thermal cutting. This type of cutting is commonly used for thicker materials and complex shapes.

Plasma Cutting

Plasma cutting uses an electrically conductive gas to create a high-temperature plasma arc that melts the metal as it cuts. It’s particularly effective for thicker conductive metals and is an excellent choice for industrial fabrication where ultra-fine precision and smoothness is not always required.

Mechanical Shearing

One of the fastest, most economical methods for producing straight cuts on flat sheets, mechanical shearing uses powerful blades that apply force along a straight line. This process is great for high-volume production runs where speed, consistency, and efficiency are the primary priorities.

What to Check Before Ordering Concrete

What to Check Before Ordering Concrete

A few simple checks can save a trip or a ruined pour.

Confirm the Right Mix Grade

Make sure that the correct strength of concrete is used for the specific job. A C20 mix is adequate for things like domestic paths, garden sheds and bases for the bases of other small structures. A stronger mix, such as C30 or above, would be more suitable for driveways and for structures such as large slabs that are to be used for structural purposes.

Calculate Your Volume Carefully

Work out the volume of your site in length x width x depth in meters, to arrive at the volume in cubic meters. Add 10% to this volume to account for all site works and for any possible concrete to spill over site boundaries. Ordering less than this volume will cost an arm and a leg.

Check Site Access

A ready-mix truck is a large, heavy vehicle. For Concrete Stroud, visit https://www.monstermixconcrete.co.uk/concrete-stroud/. Suppliers will want to know this information to determine the most suitable delivery method.

Prepare Your Formwork First

The ready-mix lorry will not wait for you whilst you finish building your shuttering around your concrete pour. Ensure your formwork is complete, checked for any leaks from the joins and the stakes are all firm and secure before the lorry arrives at site.

Know Your Pour Window

Most Ready Mix Concretes have a working life of around 1-2 hours from leaving the Plant, prior to setting. Ensure that you have booked the delivery at a time to suit yourself and your workforce. Check the weather forecast prior to ordering, as rain, frost or temperatures above 30 degrees C can affect the setting of the concrete. For local deliveries of Concrete Stroud, can deliver your local drops.

By getting all the above details correct prior to ringing, the actual pour can then run smoothly.

Which material for a fence?

A garden fence plays an important role in outdoor spaces, keeping the garden secure and creating a beautiful backdrop for your plants and garden features.

If your fences are looking tired or worn, it may be time for an upgrade. Before you do so, consider which material is most suitable for your needs. Let’s look at the different possibilities.

Composite Fencing

Composite fences are constructed from recycled wood fibres and plastic. On the plus side, they’re durable, long lasting, and low maintenance. They can, however, be a more costly option.

Steel

Steel fencing is extremely durable, very strong, and offers an excellent high security option. It is very heavy, making it tougher to install, and the appearance is generally more suited to an industrial area than a home.

Metal Balustrades

Depending on your needs, it may be worth considering metal balustrades. While they aren’t a standard fence design, these vertical metal bars are wonderful for adding a little bit of style and beauty to your garden. Made from aluminium, steel or wrought iron, metal balustrades are ideal as open railings on top of walls, around patios or decking, or alongside steps.

Vinyl

Vinyl, or PVC fencing, is plastic based, resistant to corrosion, low maintenance, and easy to install. That said, it can be slightly less robust than its composite or steel counterparts.

Aluminium

Aluminium fencing is rust and corrosion resistant, durable, and can be recycled once taken down. It can be a more expensive option, depending on the design.
