Core Guide for Stone Maintenance of Landscape Sprinkler Pools

1. Alkali prevention: cutting off the path from the construction source

Material Selection

Choose low-permeability and high-density stone materials (such as granite, which is better than marble) to reduce water infiltration.

Avoid using sea sand and add waterproofing/water reducing agents to the bonding mortar to reduce the precipitation of salt and alkali such as Ca (OH) ₂.

Waterproof Treatment

Before installing the stone, apply a special protective agent/resin adhesive on the back and sides to block the capillary tube (dry for more than 24 hours).

Prioritize the construction of concrete/stone wall retaining walls for the structural layer, with a waterproof layer and moisture-proof layer on the inner side, reserved drainage outlets, and anti-seepage measures.

Gap Control

Use large pieces of stone to cut false seams (such as cutting 200 × 200mm false seams from 600 × 600mm boards) to reduce the number of actual seams.

Insert 1mm thick stainless steel plate/PVC strip (9mm deep groove) into the gap and seal it with adhesive glue; Seal the top gap with sealant/glass glue.

2. Key construction process points

Water Quality and Paving

Use treated tap water for the fountain to avoid groundwater; When paving, the stone should be dried, soaked in water, and then dried before construction.

During wet installation, protective agents are used in conjunction with bonding mortar to ensure that the adhesive is fully and tightly spread, forming a closed barrier.

Priority given to dry hanging design

It is recommended to use stone dry hanging technology for high wall water feature pools, with overhead pipelines hidden at the bottom of the pool, which not only prevent alkali leaching but also conceal the facilities.

3. Post alkaline emergency treatment

Waterproof Blocking

Apply waterproofing agent to walls and board joints to prevent moisture from continuing to invade.

Chemical Cleaning

After testing with a stone alkali cleaning agent test block, the surface is cleaned with targeted white alkali.

Coating coverage

When cleaning is ineffective, apply epoxy polyurethane primer for protection after drying.

4. Key points of daily maintenance

Regular Inspection

Check the gap sealant for cracking and peeling every quarter, and promptly repair the sealant; Observe whether there are signs of alkali return on the surface of the stone.

Cleaning and Maintenance

Wipe surface stains with neutral cleaning agents to avoid using acidic agents to corrode the stone; Reduce watering during low temperatures in winter to prevent freeze-thaw damage.

Protection Update

Spray waterproof and protective agents on the stone every 2-3 years to enhance its impermeability.

Core logic: The maintenance of stone in the fountain pool is based on the principle of "prevention is greater than cure". Through material screening, waterproof sealing, and process optimization, the water salt migration path is cut off. Combined with emergency response and regular maintenance in the later stage, the lifespan of the stone landscape is extended.
