Five Basic Steps To Build Step Stone

The basic steps of making step stones: basic treatment --- elastic thread --- pre-laying --- laying --- jointing

1. Primary treatment

　　 Before stone construction, the ground ash, floating ash and other debris on the ground base shall be carefully cleaned up, and cleaned with a wire brush or steel flat shovel. Before construction, a cement grout bond layer shall be brushed on the ground. Grassroots treatment should pay attention to meeting the requirements of construction conditions, taking into account the needs of decoration thickness, and moisten the ground with clean water before the formal construction, but there is no accumulation of water.

2, spring line

　　 Play a vertical cross control line in the center of the field to check and control the position of the stone slabs. The cross line can be bounced on the ground and stay at the bottom of the wall. After the cross line pops up on the ground, the stone grid lines are popped up on the ground according to the stone specifications.

3. Pre-laying

First of all, in the design of the drawing design requirements, the color, texture, geometric size, surface smoothness, etc. of the stone should be strictly selected, and then pre-layed according to the drawing requirements. Adjust and exchange the errors that may occur in the pre-laying until the best effect is achieved. At the same time, pay attention to light-colored stone and stone with lower density should be coated with release agent on the back and all sides to prevent water absorption during stone paving and affect the appearance of stone surface.

4. Paving

Bonding layer: Before paving the mortar, clean the base layer and use a watering can to moisten and brush the cement slurry.

Spread the mortar layer: Determine the thickness of the screed layer on the ground according to the horizontal control line, and control it vertically and horizontally with a cross line. The stone veneer should use 1:4 (1:3) dry hard mortar after fully mixing it evenly. The hardness should be squeezed into a ball and not loose).

　　 Spread the mixed hard and dry mortar on the ground, and use a mortar board to compact it. Note that the laying width of the mortar should exceed the width of the stone by more than 1/3, and the thickness of the mortar should be about 3~4mm higher than the horizontal elevation, and the thickness of the mortar should be controlled at 30mm.

Stone paving: Before paving, pre-soak the board and dry it in the shade for later use. Perform trial paving first, align the vertical and horizontal seams, and use a rubber to hit the board (not directly hit the stone layout with a rubber hammer), and then tap the mortar to the laying height , Move the board to the side, check whether the upper surface of the mortar is consistent with the board, if there is a vacancy, dry hard mortar should be filled, and then formally pave.

Pour a layer of plain cement mortar with a water-cement ratio of 0.5 on the mortar layer. When placing it, the four corners should fall down at the same time. Use a rubber or wooden hammer to lightly hit the plank, use a level to control the paving elevation, and then install it in sequence. shop.

According to the seam requirements: the seams should be tight when paving the stone slabs, and generally no gaps are left.

5. Wipe the seams

　　 After paving is completed, grouting and jointing will be carried out 1~2 days and nights. Add mineral pigments of the same color to the cement slurry according to the color of the stone, and evenly modulate it into a 1:1 thin cement slurry, which is poured into the gap with a slurry pot or mixed with dry cement to wipe the gap. After completion, the cement slurry on the stone layout should be cleaned up with cotton silk and protected.

　　 steps are well built, but in landscape design, the effect is often affected by the site. The general site often has a topographical difference, and the clever treatment can create a layered landscape design, which is unforgettable.

　　 More importantly, respecting the height difference can reduce the amount of earthwork, reduce the damage to the current situation, and reflect the memory of the site. Commonly used height difference processing methods include steps, terrace planting belts, retaining walls, etc., using plants, landscape sketches, cultural walls, stools and other artistic processing methods to make height differences a design highlight.
