It is quite natural for masonry to start deteriorating over time. You need to have a better understanding of the main issues that affect mortar joints and stonework. It also includes construction defects, inherent defects along with problems arising from repair and inappropriate maintenance. This is where you will require the services of the reputed Sandstone restoration Glasgow company.
Typical defects
When sandstones are concerned, the constituent minerals’ strength and purity along with the matrix bonding them together tends to vary immensely. Also does its grain texture, size. This could be not just from different geological sources, but at times between beds belonging to the same quarry. Significant effect can be noticed on the mechanisms and causes of decay including conservation issues.
Cementitious matrix and grains in pure siliceous sandstones are considered to be silica based. They may experience alkaline chemical attack, thus becoming vulnerable to a few materials that are used in its repair and conservation. It includes particular ‘degreasing’ or cleaning chemicals or pure reactive limes. Also are available borderline calcareous sandstones with siliceous grains. It could perhaps be a partial lime-based cement matrix like regional ‘ragstones’. They are more prone to be susceptible to acid attacks. Also are present sandstones having significant clay content. These are distributed either all over the cement matrix thus making them weaker consequently to resist clay or concentrated clay beds. The latter might erode differentially at times in alarming fashion resulting from actions of wind abrasion and salt crystallization. Searching for the best Sandstone restoration Glasgow company will ensure deriving the best results.
Complete renewal
There are instances of extreme salt crystallization decay resulting from local sandstone getting over-saturated. This could be due to hits high clay content. Masonry in this case was probably beyond consolidation since strength got lost in cement mix while the sandstone reverted rapidly to a sand grain pile. This required complete renewal made possible by the Sandstone restoration Glasgow experts.
Generally, sandstones do pose specific challenges, especially when repair and conservation is to taken into consideration. This is the result of variation present in its constitution. Appropriate repair and conservation philosophy is based on better understanding and carrying out a detailed analysis of the involved stone characteristics. The certified Sandstone restoration Glasgow knows their job well and have the right resources and tools to carry out their work efficiently. You can discuss with them what needs to be done and the budget involved.
