Grade 1 listed Modernist apartment blocks in Highgate N6, have recently been refurbished using Sika concrete repair materials and protective coatings.

Highpoint 1 and Highpoint 2, Grade 1 listed Modernist apartment blocks in Highgate N6, have recently been refurbished using Sika concrete repair materials and protective coatings Dating from the 1930's, the blocks were designed by the Russian architect Berthold Lubetkin, a leading exponent of the new Modern Movement in Britain

They are one of the earliest examples of 'slip-formed' construction.

Lubetkin was also responsible for the famous Penguin Pool at London's Regents Park Zoo, which has also been recently refurbished using Sika systems.

Although in fairly good condition, micro cracking had occurred on the external coatings of the blocks allowing water ingress, and it was decided to refurbish using an elastic coating, thus preventing any future problems.

Architect John Winter, and structural engineers Alan Conisbee Associates, who have great experience in this type of structure, were appointed to oversee the renovation.

Main contractors, Makers UK were appointed to complete the contract, with work starting in May 2005.

The original coatings were removed, and defective concrete repaired with the Sika MonoTop concrete repair system.

SikaGard 550W, anti-carbonation, protective, decorative coatings were chosen to complete the project.

BBA approved SikaGard elastic coatings are water based with excellent UV and crack bridging properties, and can be manufactured by Sika to any colour specified by the client.

Facing tiles on Highpoint 2 were coated with Sika Elastocolor W, produced to match the original colour of the tiles.

To complete the project, all windows were repaired and painted, and new water tanks were fitted.

Other successful refurbishment projects of Modernist structures from the 1930's, recently completed by Makers using Sika materials, are Isokon flats in Hampstead, Embassy Court in Brighton and De La Warr Pavilion in Bexhill on Sea.
