Solution |
|
(1) Failure
of concrete tanking can lead to loss of water or the
ingress of ground water. Either scenario can result
in rapid deterioration in water quality.
 |
Internal repairs can be carried out using Monomix,
a high build hand apply mortar.
For large scale repairs, Monomix WS applied
using wet spray techniques is the ideal choice.
The entire surface can be overcoated with Cementitious
Coating 851 for complete waterproofing and protection
of existing concrete.
|
|
|
|
|
(2) Degradation
of brick lined reservoirs and failure of pointing
in structures, leading to leakage or the ingress of
ground water and loss of water quality test certification.
 |
After reinstatement of defective pointing with Monolevel
844SP, brickwork can be fully waterproofed and
damp-proofed using Cementitious Coating 851. |
|
|
|
|
(3) Wear and
tear of dams, weirs and spillways due to erosion,
soft water attack and freeze/thaw attack.
 |
Concrete cover over exposed aggregate caused by spalling
and erosion can be reinstated with Monolevel 844SP.
An overall application of Cementitious Coating
851 waterproofs the concrete and protects it from
further degradation. |
|
|
|
|
(4) The life
span of pipelines is limited by erosion and the effects
of soft water. Steel pipelines may be affected by
internal and/or external corrosion.
 |
The life span of concrete and cast iron pipes is extended
by the factory application of Cementitious Coating
851. It forms a hard, highly alkaline coating
which is approved for use in contact with potable
water.
|
|
|
|
|
(5) Leakage
of aqueducts, water channels and canals due to failure
of the waterproofing system. Much of the infrastructure
in the UK is now over 100 years old and showing signs
of deterioration. Years of exposure to the flow of
acidic moorland water can cause severe erosion.
 |
Repairs can be easily carried out using Flexcrete’s
mortars — such as Monomix and Monolevel
844SP, creating a newly sound structure.
|
|
|
|
|
(6) Manholes
and inspection chambers need repairing and upgrading
to improve security from unauthorised access.
 |
Manholes and inspection chambers can be re-lined with
Cemprotec E942 — a fast setting cementitious
coating for waterproofing and chemical protection.
All access areas can be fully repaired and back in
operation in as little as 24 hours.
