Benefits of LPB221 Heritage Grout
Low strength gain structural grout for building renovation
Limelite LPB221 Heritage Grout has been developed as a low strength grout to fill cracks and voids and improve stability in historic buildings. It has a compressive strength of 0.5 N/mm2 after 7 days and 1.5 N/mm2 after 28 days.
High fluidity low density hydraulic lime grout for excellent penetration
This highly fluid low strength gain, low density hydraulic lime based grout is designed for low pressure injection grouting in listed and heritage buildings and enables excellent penetration of cracks, fissures and voids deep within the substrate.
Low density grout to accommodate movement
Limelite LPB221 Heritage Grout is formulated to accommodate natural movement in the structure of old buildings, providing support while avoiding damage to existing stone or brick.
Low density grout to stabilise and protect existing structures
Limelite LPB221 Heritage Grout is ideal for filling and stabilising voids in rubble-fill masonry or stone walls, amongst other low-pressure grouting projects that require a high fluidity, structural grout.
Proven performance
Limelite Heritage Grouts are trusted by conservation professionals and proven on high profile and challenging projects including the restoration of St Paul’s Cathedral, one of the most iconic buildings in London.
