1. It is not easy to guarantee the requested consumption and thickness. [link widoczny dla zalogowanych]

5. LAMs are ideal for small roofs with complicated shapes and many details: penetrations, upstands, joints etc.
Their elongation at break often exceeds 600%.
ADVANTAGES OF LIQUID WATERPROOFING PRODUCTS

3) They are economical.
Despite this, there is always room for liquid waterproofing options.
3. Most products need an appropriate primer. Dusty, friable, irregular and cracked substrates are generally not suitable for liquid waterproofing products.

1. They create a seamless waterproofing membrane. This is not the case with all prefabricated membranes which form joints.

6. LAMs are do-it-yourself products, easy to apply, particularly where there are no technicians available. We have this problem in many [link widoczny dla zalogowanych], small and isolated Greek islands.






The ideal reinforcement - as we found after many years of experience - is an elastic, isotropic, non woven polyesteric fabric of about 50gr/m2. This fabric can make full exploitation of the LAMs elasticity.
4) The installers are numerous because the initial investment is minimal and the know-how simple and widely available.

2. Some LAMs (especially acrylics) are very vulnerable to stagnated water.


1) They exhibit a very good behaviour in the Greek climate.



5) They are accompanied by 10-year warranties.




3. They show increased bridging capabilities. When reinforced they can bridge cracks of about 1,5mm width.

Liquid waterproofing products or Liquid Applied Membranes (LAMS) have some distinctive advantages.
4. Most products are prone to blistering. Substrates should be totally dry in most cases before the application.

4. Liquid waterproofing products can be reinforced with appropriate fabrics to form a robust [link widoczny dla zalogowanych], elastic and totally impermeable membrane.
2. They are highly elastomeric. In Greece and nearby countries the kings in liquid waterproofing are acrylics, modified acrylics and modified polyurethanes.

SOME POTENTIAL PROBLEMS
Greece we use mainly APP modified asphalt membranes for the waterproofing of flat roofs. The reasons for this choice are:






2) They are quite reliable.
