We were called in to help and after some investigations a breach in the basement floor slab waterproofing was found. The concrete needed waterproofing.
This was mid-term, so arrangements were made to return and solve the problem during the summer break. Whilst the students were missing, main contractors Wilmot Dixon Sustain & Brick-Tie Preservation moved in.
Bryan’s CSSW waterproofing expertise was essential in designing a solution, which solved the localised problem, without the potential for forcing water elsewhere, to other, apparently dry parts of the basement.
As Bryan explains “A combination of improved drainage, and Safeguard’s Vandex Super, overlaid with Oldroyd XV membrane was used. our technicians carried out dust free diamond scouring of the existing and new concrete slab, before applying the Vandex, which is a proven material we’ve used many times”.
The work was a complete success, leaving the rooms ready for re-occupation within weeks.
Vandex super is a capillary active cementitious product, reacting with free lime in concrete to form a completely waterproof surface, in depth. The material remains active after application, sealing small cracks and pores, even when new water ingress points arise. Preparation and strict quality control is essential and is where our Vandex trained technicians come in so useful.
The Oldroyd XV membrane was specified to allow immediate re-occupation of the rooms. Adjacent floors were sealed with Safeguard ECS epoxy coating – new timber finishes and carpets were installed within days of the extensive works.
