25. WATERPROOFING SYSTEMS<br />
Mapeproof Mastic<br />
Bentonite paste made from natural<br />
sodium bentonite and plasticising<br />
additives for sealing elements which<br />
pass through surfaces.<br />
Mapeproof Seal<br />
Natural sodium bentonite in powder<br />
form for localised strengthening of<br />
waterproofing layers made using<br />
MAPEPROOF bentonite sheets.<br />
Mapeproof Swell<br />
Hydro-expansive, rubber-based<br />
hydrophilic sealant paste in tubes,<br />
applied using an extrusion pistol.<br />
Plastimul<br />
Bitumen waterproofing emulsion<br />
for general purpose use.<br />
