FAQs
Below are some common questions that we get asked. They are broken into three groups 1) brick and mortar 2) limestone and 3) steel lintels. We will continue to add more.
Brick & Mortar FAQs
-
Yes, damaged or deteriorating mortar can be removed and replaced with new mortar suitable for the existing brickwork. The correct mortar mix depends on the age of the property, the type of brick, and the original mortar. Older heritage properties may require lime mortar, while more modern brickwork may use a suitable cement-based mortar. Using the correct mortar is important to protect the bricks and provide a durable repair
-
Yes, it indicates an underlying problem, such as water damage or poor construction. It is important to address this issue to prevent further damage, such as brick dislodgement.
-
This is a problem known as fretting or fretting bricks. Water, which has salt dissolved in it, passes through the brickwork to its surface, blowing the front (face) off the brick.
-
Small cracks are normal with settlement. Movement in the footings are the main causes of cracks in brick walls.
-
Yes, a crack can be stitched with the use of Helifix bars. The mortar is cut out from the joint to a depth of 30mm, then washed. Manufactured grout is then installed. A stainless steel bar is inserted into the grout and then repointed with a cement or lime mix to match the original.
-
These are bricks that have become crumbly, soft and powdery, typically due to moisture and salt attack. This occurs when water enters the bricks or mortar, and as it evaporates, it leaves behind salt crystals that break down the material from within. Read more about fretting bricks.
-
There are a few reasons why dust is present including, natural weathering over time, rising damp and salt crystallisation, structural movement.
mortar at the base of your bricks can be a sign of your bricks and mortar deteriorating.this can be age or several other factors.
Limestone FAQs
-
Yes, they can.
-
Lime mortar is a traditional type of mortar made from lime (calcium hydroxide), sand, and water. It is known for its breathability, flexibility, and self-healing properties, allowing walls to manage moisture effectively and accommodate slight structural movements. This makes it a popular choice for historic buildings and conservation projects. Read more about lime mortar.
Steel Lintels FAQs
-
Over time, steel lintels above your windows (if not treated) will corrode, expand and lift the brickwork above them. At this point, those lintels need to be replaced.
