T W Read have been installing Structural Waterproofing systems for over 30 years. We specialise in the installation of Cavity Drain Membrane Systems. This includes the installation and maintenance of pump systems.

Property owners are now more than ever carrying out cellar-basement- vault conversions to their properties. This can add considerable value to the property and can create bright additional offices, cinema rooms, play rooms, bedrooms, gymnasiums, and receptions rooms. Your first call should be to a qualified basement waterproofing specialist company who s a member of the Property care association.

A survey can then be undertaken to design a basement waterproofing system to deal with any ingressing water that will have an insurance backed guarantee. After our detailed inspection and meeting with you, we will then produce a survey report and drawing detailing our findings along with all the costs associated with the basement works.

Our preferred method for all our structural waterproofing is the cavity drain membrane system but we also use cementitious tanking products to complement the waterproofing system where necessary on flat soffits, ceilings, lift shafts and externally to retained slabs and ring beams.

Our structural waterproofing systems comply with BS8102. This is the British Standard code of practice for protection of structures from water from the ground. It is advisable that all basement waterproofing must comply with this.

It is very important that a qualified waterproofing specialist designs a long-term basement waterproofing system with an insurance backed guarantee. We have seen many failed systems where drainage channels and pumping stations have not been maintained and from poor workmanship and detailing. Our surveyor holds the industry recognised Cssw (Certificated surveyor of structural waterproofing) qualification.

Our Structural waterproofing systems are guaranteed for ten years. GPI Insurance backed guarantees are also available for a one off premium.
