Case Studies | Holy Cross College – Lead Valley Refurbishment

This case study is a great example of quickly and easily the Hyperdesmo system can be applied. Hyperdesmo Particular was used for this lead valley on Holy Cross College in Bury. We always recommend this liquid as it has reinforcing fibres mixed into it when it is produced as localised reinforcement of lead valleys can be really difficult. This is especially a problem as micro cracks and splits can be difficult to see or reach. Hyperdesmo Particular offers a way to seal them whilst still offering any strength to handle any movement in the substrate they may cause.

The surface is thoroughly cleaned and the visible splits were sealed. You then prime the surface and apply a coat of Hyperdesmo Particular at around 2kg/m2. It is waterproof in a couple of hours and fully cured in 24. Job done!

I used Hyperdesmo HAA and Particular on a tricky job which combined with the great advice provided by the team at Alchimica resulted in a successful outcome and a satisfied customer. Cheers!
