Stormdry masonry protection cream has been used to treat penetrating damp at Denne Park House, a Grade II listed building in West Sussex.
Top floor rooms were suffering from internal damp problems due to water ingress. Tests using Stormdry gauges were able to determine the severity and exact location of rainwater penetration. Results showed that waterproofing treatment was required for the lower sections of the external chimney breast elevations of brick and sandstone.
masonry protection cream and Stormdry
Repointing Additive were specified as the preferred waterproofing solution. Due to its unique formulation, Stormdry
deeply penetrates masonry to form a water-repellent yet breathable barrier. This leaves no visible alteration to the natural appearance of the stone or brickwork, which was required for works to this listed building. Stormdry
Repointing Additive imparts water-repellency to mortar and improves adhesion between mortar and the brick.
masonry protection cream was applied to the external chimney brickwork and sandstone, with all mortar beds raked out and repointed using Stormdry
Repointing Additive. Upon completion of the works Stormdry
gauge tests were carried out once more and confirmed the waterproofing treatment was effective. The stone and brickwork of the chimney breasts retain their natural original appearance and water ingress has been successfully halted. The Stormdry
treatment is expected to last for at least 20-30 years.
