Flexcrete provides a full tanking system to Bolton School

A system comprising Monolevel 844SP and Cementitious Coating 851 was specified by the architects Cassidy and Ashton to provide a full tanking system for Bolton School.

With almost 2,400 pupils, the School is one of the largest independent day schools in the country. It also counts as one of the oldest schools in Lancashire, with a history stretching back 500 years. Set in 32 acres of impressive grounds, Bolton School provides a local landmark with imposing pink sandstone buildings complete with Neo-Gothic façades and turrets.

The school’s current buildings were constructed between 1930-1960. The Boys’ Undercroft building connects two sections of the school and is partly located below ground. In order to provide additional classroom space, the school wished to refurbish the Undercroft, however dampness was present on the internal brickwork walls of the structure and a repair and protection system was sought which could withstand these conditions.

Monolevel 844SP waterproof screed and pore filler was first applied by trowel at a thickness of 3mm to level the brickwork surface and provide a fair faced finish. Cementitious Coating 851 was then spray applied in two coats to provide exceptional waterproofing properties, being able to resist 10 bar positive and negative pressure. It also protects substrates from the effects of aggressive acid gases, moisture, chlorides and chemicals.

Both products are easily and rapidly applied, maintain excellent adhesion even in damp environments and are CE marked in accordance with the demands of BS EN 1504. With quick curing times and minimal time required between applications, this system allowed the work to be carried out on a fast-track basis. Fastfill, a rapid setting structural repair mortar, was also applied as a waterproof fillet to the wall/floor angle.
