Damp Proofing

Damp Proofing Solution in Great Yarmouth

A2Z offer a wide range of damp proofing solutions for the treatment of rising damp.

Rising damp can occur within buildings when the existing damp course has become defective. This results in moisture and salts from the ground rising through the brickwork and mortar joints. This process is known as capillary action. Salt laiden moisture then migrates to the plaster surfaces causing saturation and damage.

It is important at inspection stage that all possible causes of moisture ingress which may be causing or adding to the internal dampness are investigated . A2Z will carry out a full on-site evaluation of these possible causes and give specifications and recommendations for all necessary repairs.

Defects causing, or adding to, internal dampness often include; high external ground levels, render finishes continuing to the ground allowing "bridging", leaking gutters and downpipes, defective external coatings, drainage and plumbing defects.

As an environmentally friendly company, we try to avoid using toxic substances and instead, use the membrane system.



A2Z offers guttering solutions in a variety of colours, sizes and shape to fit any project. We can replace any existing guttering, soffits, bargeboards and fascias which are no longer fit for purpose.

Loft Insulation

Loft Insulation

A non-insulated household can lose one quarter of its heat through the roof. Loft insulation is a simple and effective way to reduce your heating bills.

Loft insulation is effective for at least 40 years, and it will pay for itself over time. The better insulated your home, the less energy you are likely to require keep it warm and the more money you will save in the long run.

A2Z can provide and install loft installation in your home for a resonable cost so contact us for more details.

A2Z Home Vent Core Drill Ventilator

A2Z Home Vent Core Drill Ventilator

A2Z Home Dry Vent offer a range of passive ventilation units designed to allow water vapour to escape from a building in a controlled way. The patent pending triple action filter promotes the escape of damp air with minimal heat loss. Cold draughts are restricted by a specially designed thermal core within the filter.

Condensation affects a large number of older properties due to the increase in water production brought about by modern lifestyles. At the same time, doors and windows are draught proofed and chimney flues sealed. The result can be unhealthy mould growth on cold surfaces and in poorly ventilated areas.

A2Z Home Dry Vent is designed to ventilate bedrooms and living rooms where the constant background ventilation it provides allows water vapour to escape. For kitchens and bathrooms where water production is likely to be more spontaneous, mechanical ventilation should be used.

At a typical inside temperature of 20°C and relative humidity of 70% 1 m3of air contains 0.0125kg of water, creating a vapour pressure of 1.7kPa above, which there is an increased risk of mould growth. At an air velocity of 0.09m/s A2Z Ultrovent diffuses up to 0.12kg of water per hour or 2.8 litres of water over a 24 hour period powered only by the vapour pressure differential that exists between inside a property and the external environment. Installation of the A2Z Ultrovent Core Drill Ventilator required a 132mm core drill.

Cavity drain membranes

Membranes services

Cavity drain membranes provide an alternative to conventional cementitious tanking systems, which work by holding the water back. Cavity drain membranes work on the principle of allowing water to continue to penetrate the structure but control it in the air gap and divert it to a suitable drainage point.

They do not allow pressure to build up against the internal construction and the air gap behind the membrane allows the structure to breathe and to some extent to dry out.

The membranes are lose laid on floors and fixed to walls using special plugs and sealing materials, with little or no preparation required to the substrate. Once the membrane has been fitted, wall surfaces can be dry lined or plastered directly and floors can be screeded or a floating dry board system installed.

Typical areas of use:

  • Barn conversions
  • Existing basement waterproofing
  • Retrofit
  • New Build
  • Cellar conversions
  • Structural waterproofing
  • Damp proof membranes
  • Gas barriers
