1. Forming Beam Sides only
The foundation trench is excavated a little oversized
and a suitable base is formed onto which the
reinforcement is placed using track or concrete
The beam formwork is cut into strips of the
required size and is placed either side of the
reinforcement with spacers fixed as shown to give
the required concrete coverage. The sides can have
a small bent return at the base to aid stability. Then,
uniformly backfill to within about 50mm of the top
of the beam form.
2. Using a Preformed U-Section
A U-section can easily be formed by scoring and
bending the polypropylene sheet to the required
dimensions. Erection is similar to Method 1 except
the preformed U-section is placed in the excavated
trench first, followed by the reinforcement. Spacers,
depending upon the type used, can be fitted to
either the beam formwork or the reinforcement
To form a continuous beam, the ends of each
section of the formwork can either be overlapped
or butted together and taped using a PVC tape.
Note: Spacers for both sides and base should be at a maximum of
Beam formwork can be supplied as follows:
1. In 4.5 x 2.4 sheets, which can be cut or scored and
bent on site by contractors
2. When using sides only Beamform can be cut into
strips to the contractors dimensions and delivered to
site ready for use
3. Formed into U-sections to suit site requirements and
delivered ‘flat packed’.
Continuous plastic spacer is an ideal spacer for ground
beam form work and is highly recommended.
Mesh Fix spacers are a good alternative.
Square bar spacers provide a sound support on the
base of a ground beam. Recommended for heavy beam
