Villano Wall Repairs, Brownsea Island

July 22, 2016

Constructex have begun conservation and repair works to a sea wall at Brownsea Island, on behalf of the National Trust.  

 

 

The Villano Wall is a historic masonry structure providing protection to the Brownsea Island cafe over a 40 metre length.


The wall has recently suffered extensive storm damage.

 

Phase 1 structural stabilisation works were completed by Constructex in February. Phase 2 works are now underway and scheduled for completion in August. An innovative repair solution has been devised, striking a balance between maintaining the heritage nature of the structure and providing robust longer term protection against wave and tidal actions. This includes the use of specialist underwater and marine repair mortars and grouts provided by Rockbond as well as traditional hydraulic lime materials.

 

Works include repointing and rebuilding of damaged masonry using custom Brownsea Island bricks.  

 

A remedial grouting system has been developed to backfill extensive voids found in the wall.  This will involve fitting 12mm grout delivery and test bleed points in a 1000mm by 500mm grid throughout the structure.  It is critical that pumping pressures remain low to avoid damage, this will be achieved by using the Pictor MAI P2 Pump.  

 

Removal of aquatic growth prior to works has been achieved using a non-biocidal and non-hazardous Marine Algae Cleaner and all works have been carefully designed to avoid damage to the sensitive marine environment.
