DELTA membrane systems
Sealed System
The DELTA system is recommended for soil
retaining situations such as basements
and vaults. All membrane junctions,
fixing points, service entries and protusions
can be securely sealed. If active ground
water is present or expected drainage can
(and should) be incorporated into the system.
|
|
 |
|
|
Ventilated System
Above ground, where no running water is expected,
the ventilated system can be applied. With an
air gap at the Top and Bottom, a 100 mm overlap
is all that is required. This approach provides
a sympathetic solution in
Heritage properties, as the fabric of the
building remains unchanged.
Floors
The system can be used to upgrade
damp and defective floors, insulation can
be added and it can be linked to the DPC of new
walls or to the existing or chemical DPC.

Antimould Breathable Replastering
Paint
Description
Lectros Antimould Breathable Replastering Paint
(ABRP) is a mould inhibiting microporous or “breathable”
matt emulsion for use on damp
or replastered walls.
The Lectros Antimould Microporous Replastering
Paint has been formulated with specific features:
|
•
|
High pigment volume concentration
(PVC) to allow maximum water vapour
permeability
|
|
•
|
Use of special polymer to give good
abrasion resistance of a “porous”
film
|
|
•
|
Low minimum film forming temperature
(MFFT) of the polymer (5°C) which
is ideal for newly replastered surfaces
which will be relatively cold as they
dry out.
|
|
•
|
Excellent antimould performance for
up to 2 years.
