High pressure waterjets, light scrubbing hand tools, steam, sand, copper slag or glass bead blasting, surface grinding cum polishing discs, etc along with other cleaning agents are effectively used to remove surface impurities, algal and fungal growth or unwanted coatings without damaging the original surface and bringing the original surface forward. Facades are stabilized with appropriate protective coatings later to maintain aesthetics as well as

Stone Facade Stabilization

The facade stabilization method can essentially allow for buildings to be effectively repaired both structurally and cosmetically at the same time, in a uniform manner. This can be an optimal solution for problematic historic buildings which need to keep their signature old look and feel consistent, but with modern strength and durability. By making such sites dependable with facade stabilization, Sanrachana ensures further use, safety, and enjoyment of old age vintage style charm for years to come. From replacing deteriorated stones and cladding, to decaying steel lintels, sanrachana can bring existing facade’s integrity back to its near original state. stabilization helps in addressing issues arising out moisture expansion and drying shrinkage over time of mortar, clay and bricks due to detoriation

Sectional Replacement and Restoration

Sectional Replacement involves a part of structure to be selectively removed without damaging the adjacent structure and to be rebuilt as to original shape and size.

This typically is required during strengthening or restoration activities and is done either in part or in full as per project requirement for damaged or disintegrated elements like

• Brick and stone masonry
• Disintegrated or cracked stone section
• Replacement of steel and wooden frame sections
• Replacement of damaged doors and windows
• Recasting of deteriorated RCC slab in part
• Floor, dado and elevational stone and tile cladding.
• Damaged Roofing’s
