There are 3 ways to create a suitable base for laying terrace tiles. Here are the advantages and disadvantages:

  1. Lay terrace tiles loosely on gravel - The cheapest way is the so-called "Loose Fill". In this method, the natural stones are placed on a gravel or gravel bed and gravel or gravel is poured into the gaps. The disadvantage here is that you always have loose gravel on your terrace tiles, you constantly have to fill gravel or gravel into the joints. Sweeping the natural stones is therefore very laborious, as you always sweep out the loose joint material.
  2. Lay terrace tiles on concrete - The most elaborate way with cement or concrete. This variant requires technical know-how and practice. A slope, steel mats, and expansion joints are absolutely necessary. You have to process everything more or less immediately and quickly because concrete hardens quickly. With this solution, you do not get the right bond between natural stone and cement. Afterwards, cracks form and so-called cement efflorescences occur. Concrete is known to not be frost-proof and an unsightly cement veil forms after processing that is difficult to remove.
  3. Lay terrace tiles easily and by yourself with instructions. A gravel bed made of quartz gravel and epoxy resin is best suited for the base. We made sure that the quartz gravel grain size of 2-3 cm is perfectly matched to its purpose. Therefore, you do not need a slope and the water can drain into the soil. Due to the cement-free installation, you do not have to worry about cement efflorescences or broken concrete parts. This way is frost-proof, easy to maintain and clean, water-permeable, and creates an optical highlight through our colored joint quartz gravel. Great for DIY enthusiasts, home improvement enthusiasts, do-it-yourselfers, and go-getters is that you can carry out the installation completely without a specialist company. You can get advice and any support at any time from the customer advisors and gala builders of A positive aspect of this solution is that it is durable and has almost no need for repairs.

How to lay polygonal patio slabs?

With our colored joint mortar based on quartz gravel and synthetic resin! Here you will find a brief guide for laying polygonal terrace slabs.

Laying terrace slabs requires some basic tools, such as rubber gloves, a shovel, a string, a spirit level, a rubber mallet, and a tape measure.

1. Prepare the base of the terrace.
Start with excavating the soil, fill it with recycled concrete, compact it with a hand tamper. The substructure must be level, load-bearing, and free of irregularities. Before laying terrace slabs, it should be leveled and smoothed. The terrace slabs are then finally positioned on the quartz gravel bed, see point 3.

2. Lay out the terrace slabs.
The terrace slabs must be positioned to create a uniform, appealing pattern. When placing the terrace slabs on the substructure (quartz gravel with synthetic resin), the joints should be approximately 4-8 mm wide. The terrace slabs will be laid on the quartz gravel bed. The slabs must be laid horizontally and row by row. When laying the slabs, the joint widths and depths must be maintained.

3. Finally lay and secure the terrace slabs.
To prevent the synthetic resin from hardening before laying, we recommend working square meter by square meter during installation. That means you mix enough quartz gravel and synthetic resin for about 1 sqm and lay your natural stones within a time frame of a maximum of 1 hour per square meter. This is stress-free, you make progress step by step and can easily manage your time without external factors complicating your work. To secure the terrace slabs, apply some synthetic resin to the underside before laying, preferably strip off excess and not dripping with a brush. With gentle pressure and a rubber mallet, finally secure the polygonal terrace natural stones in the substructure mixture.

4. Fill the joints.
Before grouting, we recommend impregnating the stone slab surfaces. Very important here, do not impregnate the edges as otherwise no bond can be created between the joint and the stone edge. The joints of the terrace slabs are filled with the joint mortar-synthetic resin mixture. It is important that the joint mortar mixture meets the requirements of the slab manufacturer. All stones from work hand in hand with the quartz gravel-synthetic resin mixture.

5. Seal the terrace slabs.
To protect the terrace slabs from dirt and water, they should be impregnated and sealed. Special impregnating and sealing agents can be used for this purpose.
