Solar Reflectance Index (SRI)
ASTM E1980-11 (2019)
Quantifies the surface's solar reflectance: the higher the index, the lower the substrate temperature and the lower the building's cooling demand.
Recommended CPP system In waterproofing the substrate determines whether a primer is needed, how many coats and which membrane. Adhesion is the system's critical point.
-
Roof concrete and mortar Mineral
Porous and alkaline. Needs full curing and no rising damp; otherwise the membrane blisters when it heats up.
CPP system: Imperblock Imprimación + Antigoteras, Fibrado or Membrana Hybrid.
-
Aged bituminous membrane Bituminous
Oxidised, with loose gravel and open overlaps. It can bleed through and stain light finishes if not sealed.
CPP system: Overlap repair + Imperblock Antigoteras in 2 cross-applied coats.
-
Ceramic and stoneware tiles Non-porous
No absorption: without a primer the membrane will not bond. Water ingress concentrates at the joints.
CPP system: Imperblock Imprimación + Fibrado or Membrana Hybrid.
-
Fibre cement and metal sheeting Non-porous
High thermal expansion and risk of rust at fixings and overlaps. Degrease and treat rust before waterproofing.
CPP system: Rust treatment + Imperblock Fibrado with reinforcing tape at overlaps.
-
Old acrylic waterproofing Repaint
If it retains cohesion it is a good substrate; if it is powdery or detached it must be removed completely.
CPP system: Adhesion test + reinforcement with Antigoteras or Fibrado.
-
Parapets, junctions and drains Detail point
They account for 90% of water ingress. Sharp edges and right angles tear the membrane due to lack of radius.
CPP system: Cove fillet, minimum 15 cm upstand and mesh reinforcement.
