ECOLOGICAL -GREEN PRODUCT RANGE

EnviroCrete® is a registered trade mark building system under which name we produce a variety of prefab components:

  • Envirocrete Raw (treated wood chips) is the base material that is to be considered a light weight aggregate to be used in the concrete mix instead of sand and stone.
  • Envirocrete Mix is the a light weight concrete (800 kg/m3) batched in a normal concrete batching plant.
  • Envirocrete Hollow-Core Blocks are produced in normal concrete block machine automatic or semi automatic.
  • Envirocrete Hollow-Core Slabs 1200 mm width are produced with automatic hollow-Core extruder machines and slip formers
  • Envirocrete Structural Wall Panels custom size are produced in bed trays in a concrete precast panel factory.
  • Envirocrete House System, namely a construction system based on Envirocrete wall floor and roof precast panels manufactured off-site and then constructed on site – self load load bearing dry jointed
  • Envirocrete Roof System namely a composite roofing system manufactured off-site were the main component is a Envirocrete insulating slab
  • Envirocrete Highway Acoustic Barriers. Is a fully Engineered System for highway and road noise protection. It constituted be special anecoic panels of Envirocrete

How Thermal Mass works

By alternately storing and releasing heat, high thermal mass ‘smooths out’ the extremes in daytime temperatures. In warm /hot climates where there is significant temperature variation between day and night (‘diurnal’ variation), heat is absorbed during the day and then released in the evening when the excess can be either ‘flushed out’ through natural ventilation or it can be used to heat the space as the outside temperature drops. The entire process can then be repeated the next day.

Winter Heating

EnviroCrete® Building System

makes you live in the CONFORT ZONE

True dwelling comfort at all seasons

The thermal phase shift of the perspiring EnviroCrete wall  linked to the inertia of wood concrete considerably slows the heat transfers in winter and summer prevents the penetration of the solar energy, accumulated in the walls during the day and released at night.

It has been tested that EnviroCrete structures with  a phase shift of 21 hours have a damping rate greater than 96%. This value ​​can be compared to qualitative benchmarks: walls with a phase shift of 12 hours and a damping rate of 70% are already considered very good.

EnviroCrete® WALLS

make you live in the HEALTHY ZONE

A breathable wall for a healthy home

Like a skin that breathes, wood concrete naturally regulates the humidity of indoor air thanks to the migration of water vapor. When it is overabundant, the EnviroCrete wall absorbs it without creating condensation.

Conversely, when the indoor air becomes too dry, the EnviroCrete wall releases the absorbed water vapor. The principle of absorption and return of steam increases the feeling of thermal comfort and offers the key to a healthy and ecological house

WHAT IS THE U VALUE

The finish look is course but evenly flat and does not require heavy plastering.  It also has also a pleasant texture in raw finished state.

  • Monolithical wall thickness range 18- 40 cm
  • EnviroCrete Mix density is 800 kg/m3 vs Concrete ready Mix 2400 kg/m3
  • Structural load bearing walls compression strength  3,5 N/mm2 (anti-seismic certified)
  • Zero condensate risk and very high  permeability to steam
  • Walls are breathing (diffusion resistance factor u=13)
  • Resistance to cyclic frosting and defrosting in severe weather conditions (non plastered walls)
  • Thermal insulation (thermal transmittance U= 0,34 W/m2K )
  • Sound absorption properties (10cm with plaster ‘Rw’ 38 dB)
  • Certified fire resistance in 10 cm with plaster  = REI 180

FULL COMPLIANCE WITH NATIONAL BUILDING REGULATION STANDARDS

Agrément South Africa
Department of Pubblic works Rebublic of South Africa Agrément South Africa EnviroCrete Building System

Agrément South Africa is an independent organisation that evaluates the fitness for purpose of non-standardised building and construction products and systems by applying performance-based criteria in its assessment procedure.

Where a system or product is assessed to be fit for purpose, the Board of Agrément South Africa grants it a certificate. These certificates are technical documents that:

  • Describe the system or product;
  • Summarise the assessed performance;
  • List the uses for which the subject of the certificate has been assessed to be fit
  • Give the conditions and requirements that must be met if the assessed performance is to be attained;
  • State which regulations are deemed to be satisfied by the subject of the certificate.

EnviroCrete® Building System

is approved in compliance of

SANS 10400 – National Building Regulation Standard

Our building systems has been assessed in terms of:

  • Structural strength and stability
  • Behavior in fire
  • Water penetration
  • Thermal performance
  • Durability and the maintenance required
  • The likelihood of condensation forming on the inside of the building
  • Acoustic performance
  • The applicant’s quality system.

U Value explanation

Damping rate:
The damping rate is the ratio between the amplitude of the thermal wave observed inside Delta T inside and the amplitude of the thermal wave observed outside Delta T outside It is generally expressed as a percentage.
The higher this percentage, the more the wall will absorb the heat wave and provide summer comfort.

Thermal phase shift:
The Thermal phase shift, also called  thermal inertia , represents the response time between an outdoor heat peak and that generated inside a given wall. It is expressed in hours. A Thermal phase shift of at least 12 hours corresponds to the heat peak effect felt in the evening having the heat accumulated in the wall during the day being dissipated inside and outside during the night.
