Domestic garages are designed to carry a distributed load of 2.5kN/m 2 or a concentrated load of 9.0kN. Finishes minimum: 50mm concrete screed with a minimum compressive strength of 25N/mm 2 reinforced with A142 steel mesh applied directly.
All service holes are formed during the manufacture of the slabs, our standard service notch is 200mm x 200mm. Please contact the Spantherm Technical Team if larger openings are required.
Spantherm will provide insulation levels which comply with Part L of Building Regulations England and Wales; Part F, NI and Section 6 for Scotland.

1200mm wide x 375mm deep; 900mm wide x 375mm deep; 400mm wide x 375mm deep; 600mm wide x 375mm deep. Grout - 30N concrete with an aggregate size of not more than 10mm.
