Limecrete is the lightweight, breathable, self insulating, ecological alternative to concrete.
Whether your project is the construction of a brand new eco home or the renovation of an historic building limecrete could be the flooring system you are looking for.
Our contractors forced action mixers produce limecrete of a consistent quality; quickly, efficiently and with the minimum of fuss.
Limecrete just got easier.
Our contractors customised volumetric mixer has been modified with a somewhat obsessive attention to detail. Click here for details of the features of our truck which make it perfect for the batching of limecrete.

Surface Preparation
The area to be concreted with limecrete should be clean of
top soil and vegetable matter. A hardcore base of clean hardcore
(minimum depth 150mm) should be well compacted down by use
of a vibrating plate. A limecrete floor requires no D.P.M.
as the lime method is to allow moisture to breath through
a structure.
Laying the Limecrete
Limecrete is laid in a single layer of 50mm or can be laid
at a greater thickness of 100mm by laying 2 x 50mm layers.
These 2 layers should be laid onto one another while the lower
layer is still green (no longer than 12 hours between layers)
Mixing
Limecrete should be mixed to the consistency of a floor screed
i.e., a semi-dry state, which will hold together when squeezed
by hand, wet traditional concrete type mixes will result in
excessive shrinkage. If possible a screed mixer or roller
pan mill should be used and drum cement mixers tend to result
in the mix balling.
.
Finishes
Simple limecrete over- sites can be felt finished by tamping
with a wooden or steel tamper and lightly tightened with a
timber or polyurethane float or working with a vibrating plate.
Fine surface should be screeded and tamped in a float screeding
manor and then scoured with the float and trowelled.
Aftercare
Once laid limecrete should be kept damp for 96 hours (minimum).
This may call for spraying with water during warm and hot
periods. Limecrete must always be protected from freezing
conditions for the first 10 days after laying. Traffic should
be avoided for 10 days, and thereafter-protective boards should
cover the work for 3 weeks before exposure to general traffic.
