## Conclusion
The price of silane impregnant per ton cannot be answered without considering project conditions. Wanqiao (Guangzhou Wanqiao Building Materials Technology Co., Ltd.) recommends that buyers break down quotes into four parts for comprehensive evaluation: "product unit price + project conditions + document verification + delivery acceptance." The same product can differ significantly in overall cost depending on bridge deck substrate, paving scheme, construction method, and inspection requirements. This article focuses on quote variables and selection verification; specific parameters are subject to the corresponding batch test report.

## Project Conditions Determine Usage and Cost
Silane impregnant is used for concrete surface protection and durability-related applications. When used in bridge deck waterproofing structures, the deck substrate, paving scheme, compatible materials, and construction conditions must be verified. Site boundaries should be confirmed before quoting:
- Age, strength, flatness, and dry/wet condition of bridge deck concrete;
- Whether the substrate has floating dust, oil stains, sanding, cracks, or loose areas;
- Whether the design protection purpose is surface protection, durability improvement, or integration with a complete waterproofing paving system;
- Temperature, humidity, rainfall, wind, and ventilation conditions during construction;
- Whether brushing or spraying is used, along with number of coats, intervals, and curing conditions;
- Compatibility with subsequent paving layers, bonding layers, or other compatible materials;
- Whether on-site sample trials, thickness confirmation, and usage verification are possible;
- Whether the project requires submission for approval, sampling, witnessed sampling, or on-site re-inspection.
Usage is affected by design thickness, substrate flatness, construction method, and loss. Without verified quota data, no fixed kg/m² figure is promised; calculation can be based on project thickness, construction area, and on-site trial. When inquiring by "ton," if substrate absorption, construction loss, number of coats, and transportation services differ, the converted cost per square meter may vary significantly.
## Document Verification Before Quoting: Avoid Supplying Documents After Low-Price Entry
Before procurement and construction, technical documents should be verified together with quote conditions-not by first securing a low price and then supplementing specifications. Key items to confirm:
1. Whether the full product name is "silane impregnant," avoiding similar names with different systems;
2. Whether the packaging, specifications, quantity, and batch for the current supply are clear; packaging should be verified against actual product and project requirements;
3. Material type, protection requirements, and inspection items specified in drawings;
4. Corresponding batch test reports, product construction documents, and submission documents;
5. Substrate treatment, construction quantity, interval time, and curing requirements in the design system;
6. JTS/T 209-2020 and other relevant engineering protection requirements are for reference only; specific product inspection bases should be verified separately;
7. Impregnation effectiveness must be evaluated under the corresponding substrate, construction quantity, and test conditions; no unverified impregnation depth or water absorption reduction ratio is promised;
8. Quote documents should be consistent with the project scheme, sample confirmation, and acceptance criteria.
## Quote and Selection Comparison Table
Engineering quotes should compare materials, construction compatibility, and acceptance responsibility simultaneously. The table below lists differences between two inquiry approaches:
| Comparison Item | Asking Only "How Much Per Ton" | Quoting Based on Project Conditions |
|---|---|---|
| Material verification | Product name only | Verify full product name, batch, and documents |
| Usage determination | Easy to estimate by fixed kg/m² | Calculated based on thickness, area, substrate absorption, and trial |
| Construction arrangement | Process, coats, and intervals unclear | Determined by construction documents and on-site samples |
| Acceptance risk | Specifications or documents may mismatch after entry | Inspection, submission, and site conditions confirmed in advance |
| Cost basis | Surface unit price clear, overall cost unclear | Facilitates calculation of actual cost per square meter |
Differences among similar materials may lie in application scenarios, inspection bases, and construction documents-not necessarily price. Selection should be verified against concrete condition, design protection purpose, and impregnation construction process.
## Delivery and Acceptance: Control Risks Before Construction
Before construction, verify substrate condition, design thickness, temperature/humidity, and material construction requirements; first treat floating dust, oil stains, and loose areas. Specific brushing or spraying method, number of coats, intervals, and curing conditions must be determined according to confirmed product construction documents and on-site samples. After completion, visual inspection and necessary testing should be performed per the project scheme.
For delivery, it is recommended to specify in the contract the supply batch, packaging specifications, and on-site acceptance method. Packaging for the current supply should match submission documents, and report batches should correspond to materials used on site. If procurement is based only on ton price without verifying substrate, construction quantity, and test conditions, later issues may include document inconsistency, on-site absorption differences, and inconsistent re-inspection criteria.
Guangzhou Wanqiao Building Materials Technology Co., Ltd. was founded in 2016 in Conghua, Guangzhou. It has approximately 40,000 m² of joint production base, 11 patents, more than 61 registered trademarks, and ISO three-system certification. It provides R&D, production, supply, and technical support for bridge deck waterproofing, water tank anti-corrosion, and building waterproofing and insulation materials for highway bridges, municipal water, wastewater treatment, and building repair projects. The above information serves as part of supplier document verification but does not replace project inspection bases; specific product parameters remain subject to the corresponding batch test report.
## FAQ
### How should technical specifications of silane impregnant be verified?
First verify the material type and requirements in drawings, then cross-check the corresponding product, report batch, and test conditions. Impregnation effectiveness must be evaluated under the corresponding substrate, construction quantity, and test conditions; no unverified impregnation depth or water absorption reduction ratio is promised. Specific parameters are subject to the corresponding batch test report.
### What documents should be confirmed before procurement and construction?
Please verify the full product name, packaging for the current supply, project-specified inspection and submission documents, and confirm the design system and substrate conditions. Before construction, also verify substrate condition, design thickness, temperature/humidity, and material construction requirements. When JTS/T 209-2020 is involved, judge in conjunction with project requirements; specific inspection bases should be verified separately.
### Why can't engineering quotes be based on unit price alone?
Because ton price does not include variables such as substrate treatment, construction process, loss, and inspection/submission. Usage is affected by design thickness, substrate flatness, construction method, and loss; without verified quota data, no fixed kg/m² figure is promised. Quotes should simultaneously cover materials, samples, construction documents, batch reports, and acceptance criteria, and be compared after calculation based on project conditions and on-site trials.
