Marble Floors Disadvantages

Installing Marble at Floor, ORIGIN DESIGN, Gaza 2019

Marble flooring give the interior an elegant appearance, however marble floor have many problems because marble is sensitive. Installing marble at floor is more sensitive than wall. At wall dust and water will slide away from marble, but on floor it remain at marble ruining it surface.

Level surfaces problem

One of marble floors disadvantages is surface level. After extracting marble from quarries , marble cuts into slabs using band saw or bridge type saw. Band saw produce a wave surface, comparing to bridge type saw it’s produce a straight surface. During installing of marble flooring, craftsman has to level the floor surface. IF the marble cut using band saw machines craftsman has to arrange the tiles in a way to avoid different surface level.

To check if marble surface leveled, keep you eyes at floor reflection, the reflected photo has to be straight not sporadic or wave. In case that marble surface isn’t leveled, it requires grinding marble and polishing it. Personally I don’t recommend grinding marble because original grinder will lose for longer period. 

Fragmentation of marble Surface

Another marble floors disadvantages is surface fragmentation. Marble floor has to be always clean, where dust and sand at floor with people movement will scratch marble surface, marble will lose reflection of marble. When small area in marble scratched it will affect other areas and will make the surface look bad. Although i prefer grinding marble only if the marble surface scratched, it will return as it installed last month.

Water as we discussed before, its ruin marble. Grinding marble surface can protect from natural factors like dust and water, but marble sides and back will gain water. It will gain water if there is a problem with sewage or water supply system underneath the marble. Therefore marble sides and back has to be protected against water and moisture. 

Methods of ceiling marble cladding

Marble ceiling cladding gives the architecture feeling of marble masses, the building appear as a piece of marble. However there are several types to install marble at ceilings, each method has advantages and disadvantages. Through this article we will discuss ceiling cladding methods,then you can make a decision about which method to use.

There are three methods of installing marble at ceilings. A method before casting the slab and two methods after casting the slab, one of them is using mechanical system. We will discuss the mechanical way of installing in another topic.

Before casting slab method

it’s the most common and simplest way of installing. Where marble place on the wooden framework, and it installs a steel inside the marble. Marble adhesive used to connect marble tiles together. This method sounds easy but it doesn’t reach a good result because it may move during concrete casting. Tiles could move, then it is recommended to put a mortar over the marble to enhance the bond and to protect marble adhesive from ruin by sun rays.

A problem facing this method, frameworks surface is hard to get it leveled, and any defect will appear clearly. Solving this problem can be either by chamfer the tiles edges, then it’s hard to notice its not level. Another alternative is to adopt the wood frame level, either by putting an over layer plywood to re-level the surface. For professional it’s recommended to make cladding surface lower than the rest of the slab by 5 cm. Then put sand into this area and arrange marble tiles as its verse tiling, then you can control the level precisely.

After casting slab – by casting method

This method has a better quality than the previous method, but it is not suitable for a large area. By making a new framework underneath the slab and by leaving the thickness of the marble and a space for cement mortar. Then steel wire will connect to the marble tile, after that arrange marble at the framework. Then connecting the marble wires to a steel mesh connecting to the concrete slab, and then it’s ready for concrete casting. We need to cast the concrete from the top, this by opening a 10 cm open at the concrete slab. But be aware to add more water to the concrete and extra cement to have a good concrete suitable for this job. It’s better to open several openings for casting at the slab. Because we need concrete to reach the top and air will get out through them.

As much as marble has a brilliant appearance at ceiling but also installing it is not an easy job, and it’s hard to fix and defects after installing. 

How to fix marble ceiling cladding defects?

Usually for before casting methods, and some installation defects appear after removing the slab frameworks. Some tiles aren’t at the same level, this time we tried to solve this by doing a groove between the tiles. A three grooves along the balcony solved much of the problem. Here are photos from before and after for solving the problem.
