Techspan Beam & Block is a flooring system composed of pre-stressed concrete beams with standard building blocks laid between the beams, together with split course and professional fixing, they add up, quite simply to a comprehensive flooring package.
From supply of beams only to a complete structural floor our Client need only select those elements that meet their requirements.

BEAMS
Beams are pre-stressed and are available in three profiles, designed in accordance with BS8110 using grade C60 concrete and a cover to the reinforcement to satisfy the 'moderate' exposure condition as defined in
BS8110.
Pre-stressed beams are manufactured in standard lengths of 50mm increments.
BLOCKS
Infill blocks may be standard walling or flooring blocks to meet the following specification:
Blocks shall have a minimum of 3.5Nmm2 crushing strength with a transverse point load capacity of 3.5kN on a 420mm span.
Alternatively in the absence of transverse test results a minimum crushing strength of 7N/mm2 is required.
100mm thick, solid and manufactured in accordance with BS6073: 1981. Block densities between 650kg/m3 and 2000kg/m3 are generally available.
Where blocks are built into walls of a higher strength than the infill block, then the General Contractor must provide compatible perimeter blocks.
Split course blocks have a crushing strength of 7N/mm2.
FLOOR FINISHES
The top surface of the beam and block floor is suitable for the application of one of the following

(i) Sand/cement screed applied directly over the floor area.
(ii) A timber T & G floating floor may be laid directly onto a continuous D.P.M. over a levelling screed on the beam and block floor.
(iii) When additional insulation is required, a layer of insulation material is laid over the floor, which may be completed by either a sand / cement screed or T & G floating floor on D.P.M.
