We are a specialist basement company that can provide a service to include the design and application of systems whether it be an existing space that requires full rehabilitation or a new build basement. Retro fits can be to full building regulations approval or designed to comply as a dry environment with BS8102. We are able to offer our services for the whole project or the structural waterproofing installation only. With new builds we can hand over the project at ground level as a watertight shell.

As with any credible company within the industry we have the following insurances and indemnities.

Public Liability: £5,000,000
Employers Liability: £10,000,000
Products Liability: £5,000,000

We are members of the Property Care Association, the premier trade body for the structural waterproofing, wood preservation, damp proofing, flood remediation and structural maintenance industries in the U.K. To be members we are required to have Professional Indemnity Insurance for Design & Construction (£1,000,000 indemnity limit). We are also able to offer insurance backed specialist structural waterproofing guarantees through the Construction Guarantee Services (CGS) or the Guarantee Protection Insurance (GPI).

We can make an appointment to visit the property or site depending on the type of project. For new build we can work from information provided from your architect or engineer to provide a budgetary cost before full information is available. For residential and retro-fits we can visit the property and survey the property and survey before providing a report or quotation within 14 days.

You do not generally require planning permission for existing basement spaces that are to be converted. However, if a light well is to be excavated and used as a fire escape this may require planning if it doesn’t already exist.

Generally we will put in an application for building regulations approval so each stage of works is inspected and then passed off. This could include foundation works, structural waterproofing and fire regulation rules.

For new build basements planning approval would be required but would normally be covered within the planning application for the whole build.

The majority of properties will require some form of party wall agreement where neighbours concerns can be addressed during this process. The Party Wall Act provides a positive framework for the resolution of neighbour related construction issues. It does not however prevent the formation of a basement at your home.

This depends on the type of project and the extent of works. Under normal circumstances it is not necessary to vacate the property. Access can usually be gained straight into the basement via lightwells and fire escapes at either the front or rear of the property without the need to access via the clients living space. The staircase is generally installed towards the end of the construction process.

The provision of daylight is essential for any successful basement project. Under normal circumstances natural daylight is provided at the front and rear of the property via light wells or similar structures.

To achieve a satisfactory height underpinning is sometimes required if the existing foundations are breached in our attempt to provide our clients’ preferred head clearance. The foundations of the building will be considerably strengthened as a result. If you already have the necessary head height and require a dry environment then underpinning will not be required.
