Waterproofing specialists seal leaky basement


W


aterproofing specialists, Severn Damp & Timber Preservation, installed a range of Triton Systems’


materials to deal with water ingress around two skylights, formed within the concrete roof deck over a domestic basement that extended into the garden. Following the report of visible signs of water ingress into the basement, a


waterproofing solution was designed to seal around the skylights and to encourage surface water to drain away. The gravel was removed around the skylights and the exposed brittle and cracking plastic damp proof membrane was cut back. The area was then jet washed. Mortar incorporating Triton Trimix Resin, a water and salt resistant additive, was then injected around the skylights to fill any gaps. A bottle cove fillet of Triton Fillet Seal was then applied around the skylights and coated with two coats of Triton TT55 – applied as a waterproof slurry, extending over the deck to one metre around each. A screed, incorporating Triton SBR latex admix (to improve the durability and water impermeability of the mix) was then applied around the skylights and across the whole deck area, with falls laid to prevent standing water. Finally, two coats of Triton TWS Fastcoat


were applied (over a primer coat) followed by Platon Double Drain protection and drainage


membrane installed over the coated areas. TWS Fastcoat is a single pack, moisture curing polyurethane elastomeric resin. It cures as a fully bonded and seamless layer, offering continuous and flexible protection, capable of withstanding minor building movements without cracking.

The new Sugar House Island Primary School in Stratford is making full use of the strength and stability to Magply MgO boards, which carry a full set of internationally recognised accreditations including BDA certification and which are widely specified for their excellent fire performance. To date, four full pallets of the 12mm version of the Magply boards have been delivered. The Project Supervisor for Openwood Facades, Sam Crockett, commented: “Although we have used small quantities of Magply before on other jobs, this is our first major project featuring them and we are finding them very straightforward to cut and fix.” Magply offers a fire-safe and environmentally friendly alternative to conventional plywood or OSB products. The unique production process keeps the chloride content to just 0.01%, enhancing both stability and long-term durability.
