Spray Foam For Contiguous Piling Insulation
Contiguous Piling Insulation Using ThermoFoam | Spray Foam Insulation.
Contiguous Piling Insulation using Spray Foam can protect from moisture transfer into the building or structure.
Contiguous Piling Insulation can be achieved using ThermoFoam | Spray Foam Insulation. Our Nexseal LE Closed Cell Foam can help overcome concerns of cold thermal bridging through contiguous piling and into a building or basement. Closed cell insulation is the best solution for long-term thermal mass and is a viable alternative to Shot Crete or other methods of insulation.

Where To Use Spray Foam For Contiguous Piling
Contiguous piling is commonly used to separate earth or sand from the structure being built. It’s common in situations where there’s underground basements or structures are being built into an excavated hillside. Without adequate tanking or insulation, there is a high risk of moisture and cold bridging transferring through the building assembly to cause damp, condensation and mould issues within the structure. Nexseal LE offers a superb method of providing a thermal break to separate the outside from the inside.
Basements
If you are installing a basement that sits below ground level, contiguous piling is the best way to retain the pressure from surrounding soil and materials. The piling adds structural performance to the building. Nonetheless, the piling usually requires insulation in order to prevent damp and condensation forming on the surface and degrading the structure. Closed cell foam has a strong bond to the surface and offers exceptional thermal performance.
Swimming Pools
If you have a below ground level swimming pool in your building, contiguous piling may be used to protect the structural element of the surrounding fabric of the building. In high humidity environments like swimming pools, it is vital to protect the fabric of the building from becoming damp where rot and rust may impact the structure. Closed Cell insulation offers the safest way to insulate and control moisture in these zones.
Underground Homes
Some choose to build their homes underground so that the landscape around is not spoilt. Whilst this method of building has benefits, the structural implications of heavy soil surrounding the building can create weakness, hence the need to use contiguous piling. It is vital that the insulation provision in any below ground areas is well thought out and spray foam insulation can act as the perfect, airtight solution to stop condensation and retain heat.

Gallery
Check out our Gallery where you will find some photographs of installations we’ve completed in the past. Whilst spray foam is insulation and not decoration, our experienced installation teams will always endeavour to provide a neat and tidy finish to the insulation. Nexseal LE closed cell is easier to achieve a neater finish whereas Sucraseal Open Cell expands at a faster rate to leave an undulated finish.
FAQs
Pilings are usually an irregular shape with undulations to provide the structural strength. Pre-manufactured insulation can be tricky to fix into place and there will always be air voids in the undulated zones which means airtightness is key to prevent condensation. Closed cell spray foam is the perfect solution because it can follow the curved nature of the pilings and provide a seamless, thermal layer for peace of mind.
Normally, the foam would be covered with a suitable lining when the building is complete. In habitable areas, this is mandatory as it would be with PIR board. During the construction process, if the foam is left exposed to sunlight, the UV rays can break the foam down and turn it a dark orange colour. We highly recommend painting over the foam if it is being left exposed during the construction process.
It depends on the thickness required and the available access. One team can insulation approximately 100m2 per day at 100mm thick. Good access to the install zone is important and ideally the floor area should be clear. It is also important that the substrate is dry, free first dirt and grease to guarantee adhesion. Damps surfaces can slow down the install process as our teams would need to manually dry them.
Open cell spray foam is a 0.5lb density and therefore a bit like a sponge! If moisture were to transfer through the pilings, there would be little to stop it penetrating the open cell and reducing the effectiveness of the thermal performance. We would virtually always recommend our closed cell foam for contiguous piling because it is rigid, high density, repels moisture and adds exceptional thermal performance.
The closed cell spray foam is inert once applied. It does not change at all in its performance or density providing it is not damaged by external factors. A compliant application of closed cell foam should remain adhered to the surface onto which it’s applied for the life of the structure and it will not shrink, peel away or reduce in performance. We guarantee our installs for a period of 25 years with the expected life to be much greater.
Contiguous piling should still be sufficiently tanked to stop moisture from transferring through the building assembly. Nexseal LE offers the thermal mass that reduces the dew point and therefore mitigates the condensation risk through thermal bridging.
